I think its 101 DB at 3/4 throttle.

Hiflow cats and Corsa = small chance! Limiting revs...huh... well they will look at your tac, not coilpacks output! Anyway getting back to the nightmare SVA testing, you will need to borrow airbox restrictors for starters!!

Hi, you are going to have to borrow a UK spec Exhaust system. That is the only way you will get through the SVA, if you currently have a Corsa, etc., fitted.

Depending on the station, you not even be able to sit in the car and run the revs up yourself, to 3750. The inspectors like to take Vipers for a little run around the test track that they have a each station an then do the noise test.

Not sure who in the club has a spare UK spec exhaust as "el Presidente" parted with his and it is now in NZ, I believe. Hopefully, someone will respond and help you.

Good luck

Get a failure first then you know where you stand.

I would still split the exhaust and pin it and fill it.

Wire wool or carpet works great!!!
